Abstract
Overpressure valves for hydraulic mine impellers with a valve stem designed as an extensible rod spring, which at one end carries the valve plate and, on the other hand, a tensioning device, for example a clamping nut, which it serves to adjust the pre-tension of the rod, characterized in that the end of the extensible rod, in which the tensioning device is located, is located inside the pressure chamber closed outwards, by means of the valve plate.
